Ok so I am going to get the 180watt power supply to go with the 230watt and have 2 questions. I was told I need to change the jumpers for the new power supply to work. Also I am going to get a reference pny gtx 960 4gb. So my first question is what jumpers will I need to change. And 2nd question is does anyone have a link to buy the 180watt power supply? Thanks for any help
